AIR CLWANSING AND COOLING DEVICE SPECIFICATION forming part of LettersPatent No. 626,388, dated J' une 6, 1899. Application filed November 5,1897. Serial No. 657,528. (No model.)

To @ZZ whom it 71mg/ concern:

Be it known that I, JOSEPH MCGREERY, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio,

have invented certain new and useful Improvements in Air Cleansing andCooling Devices; and I do hereby declare the following to be afull,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to new and useful improvements in an aircleansing and cooling device; -and it consists in the constructionhereinafter pointed out.

The special object of this invention is to construct a device in whichnot only is the water thoroughly commingled with the air and then thetwo separated, but also the device is kept from freezing when thetemperature is low. V

In the drawings, Figure l represents an end view of the device, theouter part of the case being removed to show the interior construction.Fig'. 2 is a transverse vertical section through the case. Fig. 3 is ahorizontal section taken through the bottoni ofthe case.

In the drawings the letter A represents an elongated case madepreferably with an offset a and having its bottom a' preferably largerthan the top portion a2. This case is provided with an air-inlet a3 atthe top and an air-outlet d4 at the bottom. Near the top it has awater-inlet B and at the extreme bottom a water-outlet b. Attached toand depending from the nozzle b of the inlet B are two deiiectors O andC', one above the other and thelower the larger. Below these deflectorsand extending transversely across the case A and spaced apart from oneanother are a number of staggered shallow pans D, which may or may nothave at one side a lip CZ. These shallow pans D are placed in the upperpart of the case A. Those of the pans D which are adjacent to that ,sideof the offset a of the case which is the underneath side are secured bytheir adjacent edge to the side of such odset. The pans at the upperside of the offset are not so secured, but are spaced apart in the sideof such offset. J ust below these pans and in the top of the bottom aare placed several transverse troughs E, such troughs being preferablymade to hold more water than may be held in one of the pans D. Thesetroughs E may be differentlyarranged. A little below the 1oWermosttrough E and to each side a receptacle or trough F is located. Anopening is left between the trough E and the receptacles F', as shown atG. J ust below the receptacles F and just above the outlet of* anotherreceptacle II is placed to one side of the case A. An overflow-pipe Khas branch pipes 7o,which comm unieate with the bottom of the troughs EE and receptacles F H. To the side of the case, away from the receptacleH and beyond its inner edge, is placed a trough I, from which depends adrain-pipe i, terminating near the bottom of the case. In the bottom ot'the case, extending from the under side of the receptacle H to thebottom of the case, and in front of the mouth of the outlet a4 areplaced perpendicular separatonplates L, V- shaped in cross section andhaving their angles toward the outlet 0:1. At the extreme top of thecase, above the water-inlet B, a steam-inlet M enters the case and has adownturned nozzle m.

Air and water enter the case at the top, the water falling by gravityand air under pressure in any of the well-known ways. As the wateremerges from the nozzle b it is thrown,

about the case by the deflectors or spreaders. The water and air are thus com mingled at the top of the case. As they pass downwardly the watercatches in the shallow pans D and runs over their edges. The offset ctand the side lips (Z of the pans D cause the Water to fall in spraytoward the middle of the device. Both at the spreaders and in iowingover the edges of the pan the water is broken up into spray, so that thewaterand air are thoroughly commingled as they pass down the case. Byhaving the pans secured at their edges to the lunder side'of the offsetwater may not run down that side of the case, but is thrown toward themiddle. It is unnecessary to secure the pans on the other side oftheoffset, as there is not any danger of the water striking that side ofthe case. When the water reaches the troughs E E and receptacles F, itpasses off through the overflow-pipes 7c K. The air ICO 2 ceases passesdown through the openings G, and any water which may pass down with theair is collected into the receptacle I-I or trough I. Should any Waterfall to the bottom of the case, it will be caught by theseparator-plates L.

It is obvious that a device like this will thoroughly commingle air andwater, so that the former is effectually cleansed from all impurities.

At the same time the air and Water are both thoroughly separated, sothat the air withut the water passes off through the outlet a When thetemperature is low enough for freezing, steam may be admitted into thecase through the inlet M. The steam passing down with the water and aireffectually prevents any freezing in the case.

The case Ais made with an odset et, so that a device of less height maybe used in a given space. In this class of devices, where baffleplatesin the shape of alternating shelves are used, there is a sufficientlength of passage, so that the air and water may be thoroughlycommingled and also separated; but in some locations it is not feasibleto use the device of such a construction, but a device of greater lengthand less width, such as a pipe, must be used. In such latter device inorder to get the necessary flow a greater length of pipe is demandedthan the space will sometimes allow. passage of the air and water, theoffset a is made, this odset compensating for the shortening of the pipein height. The length of pipe may remain the same, or in some instancesif the offset be sufficiently marked the retardation of the waterpassing through the offset will compensate for diminution in the lengthof the pipe.

In order therefore to obtain the proper Having described the invention,what yI 4o claim is- 1. An air cleansing and cooling device, providedwith the offset, a, having a water-inlet, an air-inlet, a Water-outletand an air-outlet, a series of shallow pans secured in the upper part ofthe case and at the offset, those pans which are adjacent to the underside of the offset being secured thereto and the pans adjacent to theupper side of the offset ben ing spaced apart therefrom, and a series of5o troughs, the pans and troughs being placed between the inlets andoutlets and the troughs provided with overflow-pipes, as set forth.

2. An air cleansing and cooling device having Water and air inlets atthe top and water and air outlets at the bottom, and between the inletsand outlets water pans and troughs, and below the troughs and'in frontof the airoutlet a series of'perpendicular Veshaped separator-plateshaving'their angles toward the 6o air-outlet, as set forth.

3. An air cleansing and cooling device provided at its top with anair-inlet and a waterinlet, and at its bottom with an air-outlet and awater-outlet, and between the two with sev 65 eral shallow pans, severaltroughs provided with overflow-pipes, a water-receptacle provided withoveriow pipes, a trough below such receptacle provided with drain-pi pesand perpendicular V-shaped separator-plates, as 7o set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH MOCREERY.
